摘要
在达姆施塔特 GSI 亥姆霍兹重离子研究中心，利用 HADES 装置测量了 = 3.18 GeV 质子 - 质子碰撞中 {\Lambda} 超子的 inclusive 产生。将实验数据与同一反应中各个 exclusive {\Lambda} 产生通道的基于数据的模型进行了比较。详细考虑了中间共振态如 {\Sigma}(1385)、{\Delta}++ 或 N* 的贡献。特别是，部分波分析的结果被用于解释丰富的 pK{\Lambda} 末态。模型与数据在中等快度区显示出合理的一致性，而在较大快度区则发现存在差异。测得 = 3.18 GeV 下 p+p 碰撞中的总 {\Lambda} 产生截面为 {\sigma}(pp {\Lambda} + X) = 207.3 1.3 +6.0 -7.3 (stat.) 8.4 (syst.) +0.4 -0.5 (model) {\mu}b。
